Fascinating Fact:
Ants live in organised colonies with different roles, such as workers that gather food and care for the young.
In Specialist Nature, insects are studied through simple identification clues and the jobs they do in ecosystems. Most insects have six legs, a body in three main parts, and often wings, but different groups vary in shape and lifestyle. You might find insects in soil, ponds, woodland, grassland, and gardens, where they pollinate plants, recycle dead material, hunt pests, or become food for birds and mammals. Observing antennae, wing type, mouthparts, and behaviour can help narrow down what you are looking at.
Key Terms
- Exoskeleton: A hard outer covering that supports and protects an insect’s body.
- Thorax: The middle body section where an insect’s legs and wings are attached.
- Metamorphosis: A change in body form during development, such as egg, larva, pupa, then adult in many insects.
Frequently Asked Questions (Click to see answers)
How can you tell if an animal is an insect?
An animal is an insect if it has six legs and a body split into three main sections called the head, thorax and abdomen. Many insects also have antennae, and some have wings, but the six legs and three-part body plan are the key clues.
Why are insects important for the environment?
Insects are important because they pollinate many plants, break down dead material, and help keep food chains working. They are also a major food source for birds, bats, amphibians and other wildlife, so fewer insects can affect whole ecosystems.
What is the difference between an insect and a spider?
Insects have six legs and three main body sections, while spiders have eight legs and two main body sections. Spiders also do not have antennae, and they are arachnids rather than insects.
